5-Color Universal Palette
Remarkably, a five-color palette exists which works well for many images:
- Red
- Yellow
- Blue
- Black
- White
Below are a few samples. On the left are the original images; on the right
are the five-color mosaic counterparts (scaled down to match the size of
the originals).

Unfortunately, the five-color “universal” palette (not so universal after all)
doesn’t handle greens and purples very well!
8-Color Universal Palette
Adding three additional colors (medium green, cyan, and magenta) to the
palette improves results significantly:
The main advantage of the “universal” five-color palette (red, yellow, blue,
black, and white) is that it consists of the five most basic LEGO® colors,
all of which have been available for several decades. It’s also an excellent
starting point from which to explore other color combinations. The “universal”
eight-color palette gives better results but uses uncommon colors.
